It's been several months since I've done anything in the yard and my step-father's 80th birthday is coming up and we're having a surprise party for him out back so I want everything to look nice. I've been meaning to address the lawn irrigation for a few years and finally decided to just do it. This is my count for all new spray heads. I replaced all of the existing spray heads with MP Rotators for better coverage and efficiency. I also be retrofitted the valve manifold with a new regulator, particulate screen and shutoff valve in the process.
